Anycubic Kobra 4 vs Formlabs Form 4 — documented properties and sources
PropertyAnycubic Kobra 4BEDSLINGERFormlabs Form 4RESIN
Identity
BrandAnycubicFormlabs
ClassBEDSLINGERRESIN
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra 4[1]Formlabs Form 4 3D Printer[2][3]
Release date (announcement and actual shipping)Listed on the Anycubic store from 29 May 2026 (Shopify publish date)[4]Not documented
Street price (USD; dated snapshot per entry)$279.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $379.00 ($320.90 for the EU plug variant)[4]Starting at $2,625.00 at GoEngineer, in stock, checked Aug 2026. Formlabs sells the printer as part of packages (Form 4 Complete Package etc.), so package prices are much higher than the printer-only figure[3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Shares its 260 mm cube volume and its exact machine dimensions (455.4 x 445.3 x 461.3 mm) with the Kobra X, so those two cannot be told apart on size. The difference is multicolour: the Kobra X ships with native 4-colour capability, while the Kobra 4 needs an ACE 2 Pro unit for multicolour and drying. The Kobra 4 also has a smaller 3.5-inch screen where the Kobra 3 and S1 use 4.3-inch panels[1][5][6]Three machines share this platform and are constantly conflated. Form 4: 200 x 125 x 210 mm, 50 um pixels, 18.3 kg, 480 W, one resin cartridge, NOT biocompatible. Form 4B: identical hardware but validated for 38 Formlabs materials including 15 biocompatible. Form 4L: 353 x 196 x 350 mm, 46 um pixels, 58.5 kg, 900 W, two cartridges[2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable260 x 260 x 260 mm[1]200 x 125 x 210 mm (Formlabs quotes 5.25 litres)[2][3]
Machine footprint (mm) & clearance needed (cable/spool overhang)455.4 x 445.3 x 461.3 mm for the printer; the optional ACE 2 Pro is a separate 368 x 291.5 x 236.5 mm unit[1]398 x 367 x 554 mm[2][3]
Net weight (kg)9.9 kg for the printer (ACE 2 Pro 3.7 kg); packaged 12.6 kg bare or 17.5 kg as the Combo[1]18.3 kg[2][3]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Enclosed cabinet with a hinged UV-blocking cover. Operating temperature 18-28 C[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Anycubic's table gives the construction as "Gantry system" - a bed-slinger, not CoreXY[1]Masked stereolithography (MSLA). Formlabs brands the engine Low Force Display; straight-lift peel[2][3]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s maximum print speed (manufacturer claim), 300 mm/s the default[1]Not documented
Recommended/typical print speed300 mm/s default print speed (manufacturer figure)[1]Not documented
Max acceleration (claimed, mm/s²)20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended[1]Not documented
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion")[1]Not documented
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Hardened-steel nozzle, 0.4 mm standard with 0.25, 0.6 and 0.8 mm optional[1]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)300 C maximum nozzle temperature[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C maximum hotbed temperature on a PEI spring steel build plate[1]Not documented
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)LeviQ 3.0 49-point auto-levelling with Z-offset; Anycubic claims levelling repeatability under 0.02 mm and states no manual compensation is needed[1]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection with auto resume, entanglement detection and power-loss resume[1]Not documented
Multi-material/multi-color capability or official upgrade pathMulticolour and active drying both require the separate ACE 2 Pro unit; Anycubic quotes 4 independent brushless feed motors in that unit[1]Not documented
Electronics & Power
Input voltage (110/220 V, switch or auto)Not documented100-240 VAC, 4.8 A, 50/60 Hz, 480 W[2]
Total rated power drawNot documented480 W[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Kobra OS with pressure advance and flow calibration; a built-in accelerometer drives vibration compensation[1]Proprietary. Print preparation is PreForm; fleet management is Formlabs Dashboard[3]
Connectivity, UI & Camera
Display: size, type, touch?3.5-inch capacitive touchscreen - smaller than the 4.3-inch panels on the Kobra 3 and S1 series[1][6][7]7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[2]
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus Anycubic Slicer, the Anycubic app and USB; AI spaghetti detection and object skip supported[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB, Anycubic Slicer and the Anycubic app[1]Dual-band Wi-Fi, Gigabit Ethernet (1000 Mbit), USB-C 2.0[2][3]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Standard HD camera fitted, 720p[1]Not documented
Calibration Routines & QoL
Assembly level & time from unbox to first printAnycubic claims assembly and first print within 15 minutes[1]Not documented
Materials Support
Officially supported filament listPLA, PETG, TPU 95A - and Anycubic notes TPU 95A cannot be used through the ACE 2 Pro[1]Formlabs resins across rigid, tough, general purpose, flame retardant, silicone, elastic, ceramic and castable families. Biocompatible resins require the Form 4B, not the Form 4[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)48 dB or less in standard mode and 45 dB or less in silent print mode - manufacturer figures with no distance or method stated[1]Not documented
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)One year on the complete machine (excluding gifted and second-hand machines), with component warranty periods that vary by part; the period starts on the delivery date and is suspended while a replacement is in transit. Anycubic states it will follow longer local statutory periods where they apply[8]Not documented
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedXY dimensional tolerance +/-0.15% — a manufacturer specification, not an independent measurement[2][3]
Benchmark print times (source + settings)Anycubic claims a 14-minute Benchy - a manufacturer figure with no slicer settings published, not an independent measurement[1]Not documented
Resin & MSLA
Masking LCDNot documentedLow Force Display masking LCD with a 50 um pixel size and pre-tuned anti-aliasing. Formlabs does not publish the screen diagonal or pixel count[2][3]
Light sourceNot documentedBacklight unit with 60 uniform-wavelength high-power LEDs behind collimating lenses, with integrated cooling[2][3]
Vertical print speedmm/hNot documentedMaximum 100 mm/h; average 40 mm/h at a 100 um layer height (manufacturer figures — GoEngineer publishes both, which is unusually explicit about the basis). Formlabs separately claims most prints finish in under 2 hours[3][2]
Layer height rangeNot documented25-200 um per Formlabs' own tech-spec page; GoEngineer's listing for the same machine says 25-300 um. Unresolved[2][3]
Resin vat & feedingNot documentedSingle next-generation resin cartridge; Formlabs claims 5-10x faster filling and 63% less waste. Resin tank rated for 75,000+ layers with any Formlabs material. No vat capacity published[2][3]

Manufacturer claims, independent measurements, packages and test conditions retain their source wording. FDM linear speed and resin vertical speed use different units and are not directly comparable. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
